Often the data did not agree with their predictions. This meant that the model had to be changed. The modern atomic model is the result of many scientists building on each other's work.

Atomic orbitals are the basic building blocks of the atomic orbital model (alternatively known as the electron cloud or wave mechanics model), a modern framework for visualizing the submicroscopic ...

Did you know that the concept of atomic theory was first explored over 2,500 years ago in ancient India? Long before modern science, an Indian sage named Acharya Kanad proposed the idea of ...

He suggested that an atom was a tiny solid ball. He published his ideas in 1803. This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of ...
